Nortel 1200 phones use the Alert-Info for priority distinctive ring tones and call waiting tones. The value of the Alert-Info header in incoming SIP INVITE message determines the ring tone that phone plays for incoming call. If phone is in a call already, it plays the call waiting tone that is associated with specified ring tone. The value of this header can be configured on remote end. Currently, phone supports Bellcore priority ring and call waiting tones. For Bellcore priority ring and call waiting tones, the value of Alert-Info: string can be: Alert-Info: <Bellcore-dr1> Alert-Info: <Bellcore-dr2> Alert-Info: <Bellcore-dr3> Alert-Info: <Bellcore-dr4> Alert-Info: <Bellcore-dr5> Thanks, Tarru Naval Vashistha ipDialog Support _______________________________________________ > sipx-dev mailing list > [email protected] > List Archive: http://list.sipfoundry.org/archive/sipx-dev > Unsubscribe: http://list.sipfoundry.org/mailman/listinfo/sipx-dev -------------------------------------------------------------------------------- No virus found in this incoming message.
